Does anybody know how to setup Emmet support?

Hi! Does anybody know how to setup emmet-language-server and emmet-ls? Thanks for your help!

[CesarVMB]

Install servers with Mason

:MasonInstall emmet-language-server
:MasonInstall emmet-ls

Configuration overrides

File: ~/.config/nvim/lua/custom/configs/overrides.lua

M.mason = {
  ensure_installed = {
    -- Custom
    "astro-language-server",
    "emmet-language-server",
    "emmet-ls",
  },
}

Install Emmet suport

File: ~/.config/nvim/lua/custom/plugins.lua

-- Install a plugin
{
  "mattn/emmet-vim",
  lazy = false,
},

It works!
I hope it helps someone interested in the topic.

OK, thanks! But the question was "How?"

[CesarVMB]

Thanks @siduck for the clue. No mattn/emmet-vim plugin required.

Well, I found the solution from emmet-ls.

File: ~/.config/nvim/lua/custom/configs/lspconfig.lua

lspconfig.emmet_ls.setup({
    -- on_attach = on_attach,
    capabilities = capabilities,
    filetypes = {
       "astro",
       "css",
       "eruby",
       "html",
       "javascript",
       "javascriptreact",
       "less",
       "sass",
       "scss",
       "svelte",
       "php",
       "pug",
       "typescriptreact",
       "vue",
    },
    init_options = {
      html = {
        options = {
          -- For possible options, see: https://github.com/emmetio/emmet/blob/master/src/config.ts#L79-L267
          ["bem.enabled"] = true,
        },
      },
    }
})

Finally, it works!
I hope it helps someone interested in the topic.

@CesarVMB emmet-ls is dead btw, there's "emmet_language_server" ( named in lspconfig ) https://github.com/olrtg/emmet-language-server

[CesarVMB]

Thanks @siduck for the new clue. No emmet-ls required.

From emmet-language-server:

Install emmet-language-server:

:MasonInstall emmet-language-server

Setup server: file ~/.config/nvim/lua/custom/configs/lspconfig.lua

lspconfig.emmet_language_server.setup({
  filetypes = {
    "astro",
    "css",
    "eruby",
    "html",
    "javascript",
    "javascriptreact",
    "less",
    "php",
    "pug",
    "sass",
    "scss",
    "typescriptreact"
  },
  -- Read more about this options in the [vscode docs](https://code.visualstudio.com/docs/editor/emmet#_emmet-configuration).
  -- **Note:** only the options listed in the table are supported.
  init_options = {
    --- @type string[]
    excludeLanguages = {},
    --- @type string[]
    extensionsPath = {},
    --- @type table<string, any> [Emmet Docs](https://docs.emmet.io/customization/preferences/)
    preferences = {},
    --- @type boolean Defaults to `true`
    showAbbreviationSuggestions = true,
    --- @type "always" | "never" Defaults to `"always"`
    showExpandedAbbreviation = "always",
    --- @type boolean Defaults to `false`
    showSuggestionsAsSnippets = false,
    --- @type table<string, any> [Emmet Docs](https://docs.emmet.io/customization/syntax-profiles/)
    syntaxProfiles = {},
    --- @type table<string, string> [Emmet Docs](https://docs.emmet.io/customization/snippets/#variables)
    variables = {},
  },
})

This is it!
